Kavya bought 12 dozen bananas. She gave 5 dozen bananas to her brother and used 8 bananas to make a shake. How many bananas were left with her ?
Detailed Solution for Olympiad Test Level 2: Computing Operations - Question 9

Kavya bought 12 dozen bananas. Since 1 dozen is 12 bananas, the total number of bananas she bought is:

12 x 12 = 144 bananas.
Kavya gave 5 dozen bananas to her brother:

She also used 8 bananas to make a shake. So, the total number of bananas given away and used is:

60 + 8 = 68 bananas.
To find how many bananas are left with Kavya, we subtract the bananas given away and used from the total bananas:

144 - 68 = 76 bananas.
Thus, the number of bananas left with Kavya is 76.
